Adam Wooler lived in the primitive shack for 18 months and was nearly blown away by gales. But 25 years later Adam, 47, and wife Katherine, 37, below, have spent £100,000 replacing it with an idyllic chalet with stunning views.

The eco-friendly bolthole, called The Edge, is perched on a 300ft-high cliff at Whitsand Bay in Cornwall. It is rented out for up to £2,900 a week and is booked up for most of spring and summer, earning £100,000.

Previous guests include Welsh pop star Duffy, 28.

Adam, boss of a marine services firm, said: “I bought it while I was at Plymouth university. It was one room with an outside loo and I nearly got blown away a few times.

“I couldn’t afford to do anything with it until now. It looks delightful.”
